A New Bound on the Cumulant Generating Function of Dirichlet Processes
In this paper, we introduce a novel approach for bounding the cumulant generating function (CGF) of a Dirichlet process (DP) $X \sim \text{DP}(αν_0)$, using superadditivity. In particular, our key technical contribution is the demonstration of the superadditivity of $α\mapsto \log \mathbb{E}_{X \sim
